Andres Freund e3c878ffdd Avoid need for valgrind suppressions for pg_atomic_init_u64 on some platforms. ... Previously we used pg_atomic_write_64_impl inside pg_atomic_init_u64. That works correctly, but on platforms without 64bit single copy atomicity it could trigger spurious valgrind errors about uninitialized memory, because we use compare_and_swap for atomic writes on such platforms. I previously suppressed one instance of this problem (6c878edc1d), but as Tom reports that wasn't enough. As the atomic variable cannot yet be concurrently accessible during initialization, it seems better to have pg_atomic_init_64_impl set the value directly. Change pg_atomic_init_u32_impl for symmetry.
